Description
Technical Field
The present invention relates to elevators, and more particularly to door opening operations of car doors.
Background
An elevator car operating panel or an elevator riding position operating panel is arranged in the elevator car and at the elevator riding position. Each of the operation panels is provided with a destination floor button for displaying a number of a destination floor, a door opening button for opening and closing a car door, and a door closing button, for example. As an example, a passenger registers a destination floor of an elevator car moving in a hoistway by operating a destination floor button. The destination floor key is widely a touch key such as a key or a touch panel.
In recent years, in elevators installed in public facilities and the like, a noncontact car operating panel has been introduced in which a destination floor registration operation of a car can be performed in a noncontact manner by shielding a hand from a photoelectric (noncontact) sensor or the like disposed on the operating panel for detecting shielding light.
For example, patent document 1 discloses an elevator in which a destination floor registration operation can be performed by shielding a hand from a detection area of a photoelectric sensor disposed on a car operating panel and making the sensor detect light shielding.

Disclosure of Invention
Problems to be solved by the invention
However, in the case of using a non-contact sensor such as a photoelectric sensor as in the car operating panel described in patent document 1, since a shutter such as a passenger's hand does not contact the sensor, it is easy to move the shutter beyond the detection area of the sensor against intention. For example, when the door opening state of the car door is to be extended, the door opening button of the car operation panel is sometimes pressed, but when the same door opening operation is to be performed by a non-contact sensor, a passenger may inadvertently move his/her hand out of the detection area of the sensor to close the car door against the passenger's intention, which is more likely to occur than when a touch-type operation structure such as a button is used.
In this case, the car door is closed at a timing earlier than the intention of the passenger, and thus the passenger needs to perform a door opening operation again for the purpose of taking a ride down, and the like, to newly bring the car door into a door-open state. As a result, the time required for passengers to get on and off becomes long, and the operation efficiency of the elevator is lowered.
The purpose of the present invention is to provide an elevator, which can inhibit the reduction of the operation efficiency of the elevator when the non-contact sensor detects a shielding object to perform the door opening operation of a car door.
Technical proposal for solving the problems
An elevator according to the present invention is configured to be capable of operating a door opening operation of a car door provided to an elevator car in a noncontact manner, the elevator including: a non-contact sensor that detects light shielding for a door opening operation of the car door; and a control unit configured to be capable of executing a door opening mode in which the car door is opened and a door closing mode in which the car door is closed, wherein when a change in the state of light shielding is detected from the non-contact sensor to a state in which light shielding is not detected during execution of the door opening mode, the control unit executes the door closing mode after a first predetermined time has elapsed from a first non-detection time, which is a time point of the change.
In the elevator according to the present invention, when the non-contact sensor detects light shielding again before the lapse of the first predetermined time, the control unit may execute the door closing mode after the lapse of the second predetermined time from the second non-detection time when the non-contact sensor does not detect light shielding after the re-detection.
In the elevator of the present invention, the control unit may execute the door opening mode when the non-contact sensor detects light shielding in the case where the non-contact sensor detects light shielding during execution of the door closing mode.
Effects of the invention
According to the elevator of the present invention, the door closing mode is started only after a first predetermined time elapses from a first non-detection time when the non-contact sensor does not detect light shielding. Thus, the method is applicable to a variety of applications. Even if the non-contact sensor does not detect the light shielding, the door opening state can be continued until the first predetermined time elapses. Thus, even when the passenger carelessly moves the obstacle such as a hand out of the detection area of the noncontact sensor, the passenger can take the car and lower the car without performing the door opening operation again until the first predetermined time elapses. As a result, unnecessary extension of the time required for passengers to take and drop the car can be suppressed, and thus, a decrease in the operation efficiency of the elevator can be suppressed.

Detailed Description
An elevator 10 according to an embodiment of the present invention will be described below with reference to the drawings. In each of the drawings, "Z" in the drawing indicates a horizontal direction Z parallel to the axial direction of the drive sheave 18, "X" indicates a horizontal direction X orthogonal to the horizontal direction Z, and "Y" indicates an up-down direction Y orthogonal to the horizontal direction X and the horizontal direction Z, respectively.
As shown in fig. 1, the elevator 10 is a traction elevator having a machine room 14 at the uppermost portion of a hoistway 12, and is installed in a public building such as a hospital or a care facility. A main rope 20 is suspended on a drive sheave 18 of a hoist 16 provided in the machine room 14, a car 22 is connected to one end portion of the main rope 20, and a counterweight 24 is connected to the other end portion.
The rotational power from a motor (not shown) of the hoisting machine 16 is transmitted to the drive sheave 18 via a power transmission mechanism (not shown), and when the drive sheave 18 is rotationally driven, the main rope 20 moves accordingly, and the car 22 suspended from the main rope 20 is guided by a guide rail (not shown) and moves in the up-down direction Y in the hoistway 12.
In the building provided with the elevator 10, the boarding areas 26A, 26B, 26C (hereinafter, appropriately referred to as "boarding areas 26" unless a special distinction is required) are provided for each of the different floors, and the elevator 22 repeatedly performs the lifting movement from the boarding area (the boarding area 26C in fig. 1) of the floor currently being stopped to the boarding area (for example, the boarding area 26A) of the next destination floor during the operation of the elevator 10.
Fig. 2 is a perspective view showing the configuration of the periphery of car doors 22A, 22B in car 22. As shown in fig. 2, a guide illumination LM is provided on a vertical wall 22-1 located directly above a landing 22G provided on the front side of the car 22. A car operating panel 23 is provided on the side wall 22-2 adjacent to the entrance 22G. The car operation panel 23 is an operation panel for performing an input operation of a destination floor and an opening/closing operation of the car doors 22A and 22B by a passenger of the elevator 10. The guide illumination LM is constituted by a light-transmissive elongated panel provided with a lamp (not shown) inside, and has a function of notifying the passengers that the car doors 22A and 22B are in operation by being turned on at the time of opening and closing operations of the car doors 22A and 22B, for example.
Fig. 3 is a front view showing the structure of the car operating panel 23. As shown in fig. 3, the car operating panel 23 has an operating portion 30 for determining an input operation of a destination floor of the car 22 and performing an opening/closing operation of the car doors 22A and 22B, and is provided in a central portion. The keys 31A, 31B, 31C, … (hereinafter, referred to as keys "31" unless otherwise specified) of the operation unit 30 are arranged at equal intervals in the up-down direction Y. Directly below the key 31A, a door opening key 32 for performing door opening operations of the car doors 22A and 22B and a door closing key 33 for performing door closing operations of the doors 22A and 22B are arranged in the up-down direction Y, respectively. Since the structure of the door closing button 33 is substantially the same as that of the door opening button 32, the structure of the door opening button 32 will be mainly described in the following description, and the description of the door closing button 33 will be omitted as appropriate.
Each of the keys 31 is provided with a destination floor sensor unit 34A, 34B, 34C, … (hereinafter, referred to as a destination floor sensor unit "34" unless otherwise specified) for detecting light shielding, and a door opening sensor unit (noncontact sensor) 35 for detecting light shielding in the same manner as the destination floor sensor unit 34, adjacent to the right side of the door opening key 32. Each destination floor sensor unit 34 has a function of performing the same destination floor operation as each of the keys 31 adjacent to the left side in a noncontact manner. Similarly, the door opening sensor unit 35 has a function of performing the same door opening operation as the door opening key 32 in a noncontact manner.
Here, each of the keys 31 and the door opening key 32 has a function of notifying that each operation has been accepted. More specifically, as shown in fig. 3, each of the keys 31A, 31B, 31C, … is provided with a light-transmitting portion (light-emitting portion) L-1, L-2, L-3, … (hereinafter, referred to as "light-transmitting portion L" unless a special distinction is required) in the form of a number indicating a destination floor on the front side. The light transmitting portion L is configured to emit light by lighting a lamp, not shown, provided inside the key 31. On the other hand, the door opening button 32 has the same structure as the button 31, and an arrow-shaped light transmitting portion 32L is provided on the front side. Each light transmitting portion 32L is configured to emit light. In the present embodiment, unlike the door opening button 32, the door closing button 33 is not provided with a sensor portion corresponding to the button 33, but may be provided with a sensor portion corresponding to the button 33.
Then, by pressing the key 31 or detecting a shield such as a hand by the destination floor sensor unit 34, the (call) registration of the destination floor is performed and the light transmitting unit L is lighted. Thus, when the user performs an input operation via each of the keys 31, the user can visually confirm the reception status of each input operation. In the same manner, when the door opening button 32 is pressed or when the door opening sensor unit 35 detects light shielding of a hand or the like, the light transmitting unit 32L is turned on. In the present embodiment, the key 31, the door opening key 32, and the like are used, but a touch sensor or the like may be used, for example.
Since the destination floor sensor unit 34 and the door opening sensor unit 35 have almost the same configuration, the configuration of the destination floor sensor unit 34 will be mainly described in the following description, and the description of the door opening sensor unit 35 will be appropriately omitted.
Each of the destination floor sensor units 34 is provided with a substantially rectangular hole formed so that both ends are bent in the same direction, and each of the rectangular holes is covered with a light-transmissive protective plate 37A, 37B, 37C, … (hereinafter, referred to as "protective plate 37" unless otherwise specified), as shown in fig. 3. A reflective photoelectric sensor in which a projector and a light receiver are integrated is housed inside each rectangular hole of each destination floor sensor unit 34, and light is emitted from the projector, and the presence or absence of an object is detected based on a change in the amount of light received by the light receiver from the object.
Fig. 4 is a cross-sectional view schematically showing the positional relationship between the destination floor sensor unit 34 and the detection area P. In fig. 4, the detection area P is shown by hatching, and structures other than the destination floor sensor section 34 and the detection area P are appropriately omitted. As shown in fig. 4, the destination floor sensor unit 34 is configured to be able to adjust the light receiving amount (sensor sensitivity) on the light receiving side, and detect light shielding of an object (shielding object) in a predetermined detection area P. As shown in fig. 4, the detection area P is set to be a spatial area including a position separated by a distance X1 in the horizontal direction X from the destination floor sensor unit 34 to a position separated by X2 in the horizontal direction X when 0mm×x1 < X2.
As shown in fig. 3, the car operating panel 23 further has a display portion 44. The display unit 44 is configured by, for example, a liquid crystal display, and displays, for example, information indicating the direction of movement (lifting) of the car 22, the passing floor of the car 22, and other passengers. The display portion 44 is provided at a position above the operation portion 30 so as to be easily visible to a passenger. As shown by the broken line in fig. 3, a speaker SP for outputting sound is incorporated in the car operating panel 23. The speaker SP has a function of generating a sound for notifying passengers of the door opening operation, the door closing operation, and the like of the car doors 22A, 22B.
The car operating panel 23 having the above-described structure is electrically connected to a control device 46 (see fig. 1) provided in the machine room 14 (see fig. 1). The control device 46 is a computer having a CPU, a memory, and the like, and performs operation control of the car 22 based on destination floor registration performed in response to an input operation or the like performed via the car operation panel 23 or the like. The memory stores various control programs for controlling, for example, drive control of the hoist 16, opening and closing control of the car doors 22A and 22B, the light transmitting portion L of each key 31, the light transmitting portion 32L of the door opening key 32, lighting control of the guidance illumination LM, the speaker SP, and the like, respectively. The CPU reads out and executes these programs from the memory, thereby realizing smooth operation of the elevator 10 by the control device 46.
In the elevator 10, the opening and closing of the car doors 22A and 22B are also controlled by the control device 46. A control program related to the destination floor registration of the car 22 is stored in the memory of the control device 46. The CPU reads the control program from the memory, and the control device 46 executes the door open mode and the door close mode. Here, the door opening mode is a mode for moving the car doors 22A, 22B in the door opening direction and holding the doors 22A, 22B in the door opening state. The door closing mode is a mode for moving the car doors 22A, 22B in the door closing direction, in other words, in the direction of the fully closed state.
Here, a flow of the opening/closing control of the car doors 22A, 22B using the door opening sensor unit 35 in the control device 46 will be described with reference to fig. 5. Fig. 5 is a flowchart showing a flow of the opening/closing control of the car doors 22A, 22B by the control device 46 when the door opening sensor unit 35 detects light shielding.
As shown in fig. 5, when the door opening sensor unit 35 detects light shielding, the control device 46 determines whether or not the door can be opened (steps S1 and S2). The state in which the door can be opened includes a state in which the car 22 is stopped at the boarding portion 26 and the door-closed state is not necessarily maintained. Thus, even if the door opening sensor unit 35 detects light shielding, the notification sound does not sound when the car 22 is not in a door-openable state, and the light-transmitting portion 32L of the door opening button 32 and the guide illumination LM do not blink. Therefore, passengers in the car 22 are not unnecessarily guided.
In step S2, when determining that the door is openable, the control device 46 executes the door opening mode after a predetermined standby time elapses, in addition to the door closing mode (steps S3, S4, S5).
On the other hand, when the door closing mode is being executed, the control device 46 executes the door opening mode without waiting for a predetermined standby time to elapse (steps S3 and S5). This can quickly bring the car doors 22A and 22B into the open state.
In the present embodiment, as described above, when the door opening sensor unit 35 detects light shielding during execution of the door closing mode, the door closing operation of the car doors 22A, 22B is started without setting a predetermined standby time, but the door closing operation of the car doors 22A, 22B may be started after the predetermined standby time. However, when the predetermined standby time is set, it is preferable to set the standby time shorter than the standby time in the case where the door closing mode is not being executed as shown in step S4.
In step S5, the control device 46 generates a predetermined notification sound via the speaker SP when the door opening mode is executed, and blinks the light transmitting portion 32L (see fig. 3) of the door opening button 32 and the guide illumination LM (see fig. 2) of the depending wall 22-1. The predetermined notification sound is, for example, a intermittent sound such as "beep. Thus, even in a state where it is difficult for the passenger to visually confirm the light-transmitting portion 32L of the door opening button 32 in a state where the passenger shields his/her hand from the door opening sensor portion 35, the detection state of the door opening sensor portion 35 can be easily grasped.
Instead of the intermittent sound, continuous sound may be played through the speaker SP or the car doors 22A and 22B (see fig. 2) may be guided as sound during the door opening operation. As described above, by generating a predetermined notification sound during the execution of the door opening mode, for example, in the case where the door opening mode is executed by the door opening sensor portion 35 detecting the baggage or the like of the passenger, the passenger can be promptly notified that the door opening sensor portion 35 is detecting the baggage. Moreover, the method has the following advantages: the passenger withdraws the baggage from the detection area of the door opening sensor unit 35, and the door opening mode is terminated promptly, whereby the operation of the elevator 10 can be made smooth.
Next, as shown in fig. 5, when the door opening sensor unit 35 does not detect light shielding (step S6), the control device 46 executes the door closing mode after a first predetermined time (for example, 3 seconds) has elapsed from the time when light shielding is not detected (first non-detection time) (steps S7 and S15).
According to the above configuration, even if the door opening sensor unit 35 does not detect the light shielding due to the passenger carelessly moving the hand blocked in the detection area of the door opening sensor unit 35 out of the area or the like, the door closing mode is started only after the lapse of the first predetermined time.
Here, when the door opening sensor unit 35 does not detect light shielding in the above-described step S6, in other words, when light shielding is not detected, the control device 46 preferably stops the notification sound or the blinking of the guidance illumination LM generated in step S5. This makes it possible for the passenger to immediately notice that the door opening sensor unit 35 does not detect light shielding.
In step S7, after the lapse of the first predetermined time, the control device 46 ends the door opening mode executed in step S5, in other words, the process proceeds to the door closing mode of step S15. This makes it possible to hold the car doors 22A and 22B in the open state until the first predetermined time elapses.
According to the above configuration, it is possible to hold the car doors 22A and 22B in the open state, and also, in the case where the passenger wishes to lengthen the open state, it is possible to easily take countermeasures such as shielding the detection area of the open sensor portion 35 again with his/her hand, and it is possible to suppress occurrence of the door closing mode being executed against the intention of the passenger.
On the other hand, as shown in fig. 5, when the door opening sensor unit 35 detects light shielding again before the lapse of the first predetermined time (step S8), the control device 46 executes the door opening mode (step S10) after the lapse of the predetermined standby time (for example, 0.3 seconds) (step S9).
In step S10, when the door opening mode is executed, the control device 46 generates a notification sound via the speaker SP and blinks the guidance illumination LM and the light transmitting portion 32L of the door opening key 32, as in the case of step S5. As a result, the passenger can easily grasp the light shielding detection state of the door opening sensor unit 35 as in the case of step S5.
As shown in fig. 5, when the door opening sensor unit 35 does not detect the light shielding (step S11), the control device 46 measures a time from a time point at which the detection is stopped (second non-detection time point), and after a second predetermined time (for example, 3 seconds) has elapsed from the measured time (hereinafter, referred to as "measurement time") (step S12), the door closing mode is executed (step S15).
Here, the control device 46 ends the notification sound generated through the speaker SP in step S10, the guidance illumination LM, and the blinking of the light transmitting portion 32L of the door opening button 32 when the light shielding detection of the door opening sensor portion 35 is stopped in step S11. Therefore, the passenger can easily grasp that the door opening sensor portion 35 does not detect light shielding. On the other hand, the control device 46 continues the door opening mode executed in step S10 until the second predetermined time elapses in step S12 and the process proceeds to step S15. This makes it possible to hold the car doors 22A, 22B in the open state until the second predetermined time elapses. As a result, when the door opening state is desired to be extended, the passenger can easily take a countermeasure of shielding his/her hand from the detection area of the door opening sensor unit 35 before the door closing mode is executed.
As shown in fig. 5, when the door opening sensor unit 35 detects light shielding again before the second predetermined time elapses (step S13), the control device 46 resets the measurement time measured in step S12, that is, sets the measurement time to 0 seconds (step S14). Thus, even when the light shielding is detected again in step S13 and the light shielding is not detected by the post-light-shielding door opening sensor unit 35, the door closing mode can be executed after waiting for a second predetermined time (for example, 3 seconds) to elapse in step S12.
Next, as shown in fig. 5, the control device 46 returns to step S10, executes the door opening mode again, and makes the guide illumination LM and the light transmitting portion 32L of the door opening key 32 blink.
Then, when a second predetermined time (for example, 3 seconds) elapses from the time when the light shielding of the door opening sensor unit 35 is not detected and the light shielding is not detected again by the sensor unit 35 (steps S11 and S12), the control device 46 executes the door closing mode (step S15) and ends the series of opening/closing control processes of the car doors 22A and 22B.
As described above, when the door opening mode is executed, if a change from the state in which the door opening sensor unit 35 detects light shielding to the state in which light shielding is not detected is made, the control device 46 executes the door closing mode after a first predetermined time has elapsed from the time of the change, that is, the first non-detection time. When the door opening sensor unit 35 detects light shielding again before the first predetermined time elapses, the door closing mode is executed after the second predetermined time elapses from the second non-detection time point when the door opening sensor unit 35 detects no light shielding again after the detection again.
Thus, even when the passenger shields his/her hand or the like from the door opening sensor unit 35 and moves the hand out of the detection area of the sensor unit 35, the door closing mode is not executed if a predetermined time has not elapsed. When the light shielding is detected again by, for example, shielding the hand again before the predetermined time elapses, the door closing mode is not executed if the predetermined time does not elapse since the light shielding is not detected again.
Therefore, when the passenger unintentionally moves the hand blocked by the door opening sensor unit 35 out of the detection area, the door closing mode is not started at the time when the detection is made by the sensor unit 45, and even when the detection is made, the door opening state can be maintained by blocking the hand again by the door opening sensor unit 35, or the like. Therefore, there are also the following advantages: while the car doors 22A and 22B are kept in the door-open state, the door-open state can be maintained by shielding the door-open sensor portion 35 from time to time without continuously shielding the door from the door-open sensor portion 35.
According to the elevator 10 of the present invention, the door closing mode is started only after a first predetermined time elapses from a first non-detection time point at which the door opening sensor unit 35 does not detect light shielding. Therefore, even if the door opening sensor unit 35 does not detect the light shielding, the door opening state can be continued until the first predetermined time elapses. Thus, even when the passenger carelessly moves the obstacle such as a hand out of the detection area of the door opening sensor unit 35, the passenger can take the car 22 to and lower the car without performing the door opening operation again until the first predetermined time elapses. As a result, the time required for passengers to take and drop the car 22 can be suppressed from being unnecessarily prolonged, and thus, a decrease in the operation efficiency of the elevator 10 can be suppressed.
In steps S7 and S12 of the above embodiment, the control device 46 may cause the speaker SP to emit a different sound from the sound generated in steps S5 and S10 while waiting for the passage of the first predetermined time and the second predetermined time, respectively. Thus, the method has the following advantages: the passenger easily recognizes that the door opening sensor portion 35 does not detect light shielding, and the car doors 22A, 22B will be opened soon.
In the above-described embodiment, in steps S5 and S10, the control device 46 generates the intermittent sound via the speaker SP and blinks both the guidance illumination LM and the light-transmitting portion 32L of the door opening key 32 during execution of the door opening mode, but may blink only one of the guidance illumination LM and the light-transmitting portion 32L of the door opening key 32 while generating the intermittent sound. The control device 46 may control not to blink the guide illumination LM and the light transmitting portion 32L by generating only intermittent sound through the speaker SP.
In the above embodiment, the first predetermined time and the second predetermined time are each 3 seconds, but may be set longer than 3 seconds or shorter than 3 seconds depending on the use condition of the elevator 10. The two predetermined times may be set to different lengths.
The present invention can be implemented by adding various improvements, modifications, or variations to the knowledge of those skilled in the art without departing from the gist of the present invention. Further, any of the specific matters of the invention may be replaced with other technical matters within the scope of the same actions or effects.
